To @Zt whom t 77mg/ cori/cern:

Be it known that We, JACOB S. HAYE and FRANCIS M. I-IUMPHEEY, ofPendleton, in the county of 'Umatilla and State of Oregon, have inventeda 'new and useful Improvement in lVrenches, of which the following is aspeciication. l

This invention is a combined nut and pipe Wrench; and it'consists incertain novel constructions and combinations of parts, as will behereinafter described, and pointed out in the claims.

In the drawings, Figure l is a side view of our improved Wrench. Fig. 2is a face vieW of same. Fig. 3 is a longitudinal section.

Fig. 4 is a detail longitudinal section on the line at 4., Fig. 3. Fig.5 is a detail cross-section on the line 5 5,V Fig. 4. Figs. 6 and 7 aredetail cross-sections on the lines 6 6 and 7 7, respectively, of Fig. 3;and Figs. 8, 9, and l0 are perspective views of details of construction.

The Wrench is shown as formed with a bodysection A and a handle-sectionB. The section A has a jaw a and a shank C, made tubuiar, slotted alongits inner face from the jaw a nearly to its lower end and provided atits lower end with the collar-rin g D. This shank is provided with thespring-tongues E,formed, preferably, by slitting the tube at. e, suchtongues being free at their lower ends and provided at such ends withteeth or projections E, which are arranged opposite each other, pressinward, and engage With the serrations of the handle-shaft, presentlydescribed.

Vithin the shank C We form guides at F for rails f on the'handle-section B, which slides longitudinally in the shank, as shown.The handle-section has the jaw b, provided with the pivoted toothedblock H, and is formed with longitudinal side slots B', in which theteeth or projections E' extend into position to engage the serrations ofthe shaft I. This shaft lis connected With the handle 'i and extendsWithin and turns in the handlesection B, its turning being limited by apin J, operating in slot j. We form this shaft with longitudinal rows ofteeth or sei-rations I,Which alternate with plain untoothed spaces t',and it may be turned to bring the serrations into engagement With thespring-tongues or to bringv the plain spaces t opposite such tongues, asmay be desired, facilitating the adjustment of the sliding jaw and thelocking thereof in any desired adj ustment by the simple turning of thehandle.

The block H is pivoted at h to the jaw b and has a rounded toothedportion 7L' and a projecting point or beak h2, beneath which bears thefree end of the spring J, which tends tp press the block H firmly incontact with the pipe or other object being turned.

Having thus described our invention, what We claim as new, and desire tosecure by Letters Patent, is-

l. A Wrench comprising the body-section having a jaw and a tubulaishankprovided with spring-tongues having teeth or projections, and thehandle-section having a shaft provided with serrations for engagement bysaid projections substantially as described.

3. A Wrench consisting of a body-section having a jaW and a shankprovided with spring-tongues and a handle-section sliding longitudinallyin said shank and provided with a shaft having rows of serrations andjournaled lwhereby it may be turned to set the serrations into and outof engagement With the tongues substantially as described.

4. A Wrench comprising the body having a jaw and a shank provided with aspringsupported tooth portion, and the handle-section having a shaftprovided with serrations and rotatable to set such serrations into andout of engagement with the spring-supported tooth portion substantiallyas shown and described. p

5. A wrench comprising the body having a jaw and a shank provided with asprng-V tion when engaged with said tooth substansupportedoothand thehandle having a tially as described'. shaft provided With a series ofratchet-teeth JACOB S HAYE or seri'atons the shaftV being capable of be-1 f 5 ing turned whereby its ratchet-teeth may be L RANCIS M HUMPHREXset into and out of engagement with Jshe Witnesses: spring-supportedtooth, and the handle being E.
